I've been working on an update to my Greek NT Gateway at
http://www.ntgateway.com/greek.htm. The updated version of Marc
Huys' Greek Grammar on the web, which Carl mentioned, is indeed
very useful (new URL http://greekgrammar.com/). I am also happy to
see, following a link from there, that someone has uploaded a key
map for SPIonic
(http://latin.about.com/homework/latin/library/blSPIkeymap.htm).
This is going to help me very much -- twice this summer I have
examined doctoral / masters theses that needed help with finding
everything on the SPIonic font, including one that never found the iota
subscript!

I'd really appreciate some help from b-greek with one resource that
has been suggested:

The web site on this looks interesting, but I don't have a Palm
Personal Organizer so cannot review this suggestion. Would
someone with a Palm Personal Organizer be kind enough to have a
look at this for me and provide some brief comments? I'd be really
grateful.
